scroll down for image....next to last post.... I built this using the stock mag catch with a roughed up surface (300 grit paper). I then wrapped the end with clear packaging tape, to form a mould, and mixed up some JB Weld, poured it in, and let it set up. $18 for the mag catch from
http://shop.cz-usa.com/ and the JB Weld I already had laying around. I have used it during 2 practice sessions, but not in competition(USPSA), yet. I will report back in 3 months, if it lasts that long, on how it holds up.
